Sure thing. Here's the best I could find, an interview between Bungie's PC Lead and PC Gamer. They won't explicitly use Dedicated Servers, but player's accounts will be tied to Battle.net. Source:
LinkYet, over on Polygon, Bungie's Engineering Lead stated: "Every activity in Destiny 2 is hosted by one of our servers". Source:
LinkTo me it looks like the same thing they did the first time. A mix of P2P and client-server connections. Though Destiny 2 still won't have true Dedicated Servers, it will still have a form of client server hosting which will be better than the original. More secure, less drops, faster, etc. all to support the new PC platform. For example, to run a raid, a player will still need to host it, but the raid itself will be validated by the "raid activity" server.
